An Englewood man was killed Wednesday morning in a tractor-trailer accident on the New Jersey Turnpike in Elizabeth.

Cristian G. Vergara, 22, was driving a tractor-trailer in the truck lanes of the turnpike near mile marker 100 at about 1:40 a.m. when he apparently ran off the highway, struck a guardrail and the center concrete barrier, which caused the truck to flip, police said.

Vergara died from his injuries, Trooper Charles Marchan, of the state police, said.

No one else was injured in the crash, Marchan said. But what caused Vergara to run off the road remains under investigation.
